Investigating kinematics and spatial distribution of multiphase gas in the CGM
The circumgalactic medium (CGM) is a multiphase and ionized plasma that surrounds and is gravitationally bound to galaxies. There is much that still needs to be understood about the spatial distribution, thermodynamics, and kinematics of circumgalactic gas. We can probe these properties by looking at the column densities of ions that trace different phases of the CGM gas. In particular, at this conference I will present the spatial and kinematic relationships between hot and cold gas in Milky Way-like galaxy simulations using MgII and OVI as tracers for the cold and hot gas, respectively. These ions are relatively easy to observe, allowing for comparison with relevant QSO spectra from, e.g., the KODIAQ or COS-Halos surveys.
